Settings for API limitations
Currently, the API is very strict and can only generate 3 links per IP per hour (if I understood correctly), before banning for one hour, and banning for 1 month if we try to hit the API above 6 links per IP per hour.
I wrote a Weechat module to shorten URLs using the API and got banned. I manually updated the limitations by end (hardcoding them), but having a setting for it would really be helpful.
I can try to make a clean PR for this, although I do not know much of Perl.
